At age 10, she was taken from her biological parent's home. At age 14, she was be a runaway who was in a grocery store when a man offered her a modeling job that turned into a kidnapping case. She was forced into prostitution.

"A man approached me and asked me if I wanted a modeling job," said Brittany.

She said she was hungry and needed a shower and a change of clothes so she said "Yes."

"He took me to a place where he told me I was going to do my first modeling job and he told me that I would have to go up to this man's apartment and told me to do inappropriate sexual things to him," said Brittany.

She said she refused, but refusing was not an option.

Brittany said she was beaten and locked in a car.

"The minute he locked the car door I felt like I was kidnapped because I wasn't willingly going with him," said Brittany.

She was driven to a house in Chicago.

"They took my clothes off and made me take pictures, put them on craigslist, basically sold me to people who replied to the ad," said Brittany.

Brittany said she lived that life for months. She said she now tells her story to help others because sex trafficking is not just overseas or in big cities.

Brittany said she will keep telling her story to anyone who will listen.

"It made me realize, I have a voice and I need to advocate for other people to help them and put an end to it, hopefully," said Brittany.

Brittany said that she was saved from trafficking by a police officer. A sting at the house she was being held in in Chicago led to her arrest.

During the arrest, Chicago officers found out she was only 14.

Brittany was sent back to Iowa, entered the foster care system and was adopted.
